With a wide selection of display and measurement modes, automatic gain control and data-logging, the CG100 range of corrosion thickness gauges is ideal for measuring coating and material thickness as well as for locating pits, flaws and defects in materials.
The Elcometer CG100 ultrasonic corrosion thickness gauge is available in four models - from an entry level CG100B to the top of the range CG100ABDL+.

CG100 Features Explained
Repeatability / Stability Indicator
Consisting of 6 vertical bars, when all the bars are fully illuminated and the last digit on the digital thickness value is stable, the gauge is reliably measuring the material thickness.
High Speed Scan with Minimum Thickness Display
By significantly increasing the measurement refresh rate this mode allows the user to make scanned passes over the test material. The smallest thickness value is held in memory and displayed when scanning is complete. This feature can also be used in conjunction with the minimum & maximum limit alarm feature (model dependant).
Differential Mode
Once a user defined nominal thickness value has been set, the gauge will display the +/- thickness difference from the nominal value entered.
Limit Alarm Mode
The user can define minimum and maximum thickness limits. If the measurement falls outside the upper or lower limit a red LED will light and the beeper sounds. A green LED will light to indicate an acceptable thickness.
V-Path Correction
Dual element transducers consist of a probe with two crystals (one to transmit and one to receive the sound pulse). The crystals are separated by an acoustic barrier - generating a 'V-shaped' sound path as the sound travels from one element to the other.
This path is slightly longer than the direct path therefore V-path correction is used to calculate the correct thickness.
CG100 Measurement Modes Explained
 |
Pulse - Echo Mode (PE): The normal display mode, measures the total thickness from the base of the transducer probe to the material density boundary (typically the back wall). Ideal for pit and flaw detection. |
 |
Pulse - Echo Temp Comp Mode (PETP): Similar to the PE mode, PETP takes into account and compensates for the variations in measurement caused by temperature variations. |
 |
Echo - Echo Mode (EE): Also known as the ThruPaint? Mode, EE ignores the coating thickness, displaying the material thickness from the top surface of the material to the material density boundary. |
 |
Echo - Echo Verify Mode (EEV): The echo-echo verify mode measures by comparing the values between 3 reflections and is commonly used to eliminate errors from surface coatings and to make measurements in multiple layered materials. |
 |
Coating Only Mode (CT): Displays the thickness of the coating applied to the material. |
 |
Pulse - Echo Coating Mode (PECT): Displays both the material thickness (PE) and the coating thickness (CT) at the same time. |
